What is troika-worker-utils?

The troika-worker-utils package provides utilities for managing and communicating with web workers in JavaScript. It simplifies the process of offloading tasks to background threads, allowing for more efficient and responsive applications.

What are troika-worker-utils's main functionalities?

WorkerPool

The WorkerPool feature allows you to create a pool of web workers to handle multiple tasks concurrently. This can be particularly useful for tasks that are computationally intensive and can be parallelized.

const { WorkerPool } = require('troika-worker-utils');

const pool = new WorkerPool({
  maxWorkers: 4,
  workerScriptURL: 'path/to/worker/script.js'
});

pool.postMessage({ task: 'heavyComputation', data: { /* some data */ } })
  .then(result => {
    console.log('Result from worker:', result);
  });

createWorker

The createWorker feature allows you to create a web worker from a function. This is useful for defining worker behavior inline without needing a separate worker script file.

const { createWorker } = require('troika-worker-utils');

const worker = createWorker(function() {
  self.onmessage = function(e) {
    const result = e.data * 2; // Example computation
    self.postMessage(result);
  };
});

worker.postMessage(10);
worker.onmessage = function(e) {
  console.log('Result from worker:', e.data); // Should log 20
};
